    • PROBLEM TO BE SOLVED: To achieve a communication apparatus capable of accurately analyzing received information.
      SOLUTION: The communication apparatus is configured to execute the detection processing of received information from received information by radio communication, wherein a wave detection section inputs received information superimposed on a carrier signal, and generates a wave detection signal containing the received information, and an equalization processing section corrects distortion contained in the wave detection signal, that is, distortion generated in a radio communication path, and training data for setting the optimal equalization characteristics of the equalization processing section and a synchronizing signal for training data detection are set in a packet. A reception section detects the synchronizing signal, thereby reliably executing training processing using the training data.

    • PROBLEM TO BE SOLVED: To provide a communication apparatus accurately analyzing received information. SOLUTION: In a configuration for executing processing to detect received information from a signal received in wireless communication, a detector generates a detection signal including the received information by inputting the received information superimposed on a carrier signal, and an equalizer corrects distortion contained in the detection signal, namely, distortion generated on a wireless communication path. The received information is acquired by inputting the signal corrected in the equalizer to the detector comprised of e.g., a comparator or the like. In this configuration, the distortion generated on the communication path is corrected in the equalizer and the receiving information is acquired from the corrected signal, thereby performing accurate information transmission even during e.g., communication of a high transmission rate.

    • PROBLEM TO BE SOLVED: To perform appropriate propagation path estimation using amplitude information of a reception signal.
      SOLUTION: In a receiving apparatus, a detection unit 102 acquires a detection signal sequence by extracting amplitude information of an OOK modulation signal sequence obtained by performing OOK (On Off Keying) modulation on a known CES (Channel Estimation Sequence) constituted of data "0" and "1", a "1" detection section 1042 acquires an extraction signal sequence by extracting only a sample value corresponding to the data "1" from sample values of the detection signal sequence, and a correlation arithmetic operation section 1043 arithmetically operates a correlation between the extraction signal sequence and the CES. A propagation delay estimation section 1044 then estimates a propagation delay amount of a CIR (Channel Impulse Response) from the arithmetic operation of the correction, and an amplitude coefficient estimation section 1045 estimates an amplitude coefficient of the CIR from the arithmetic operation of the correlation.
